کتاب Apps and Services with .NET 7 (برنامه‌های کاربردی و سرویس‌ها با دات
نت 7)، اثر مارک پرایس بازگشته است تا شما در جالب‌ترین و رایج‌ترین
فناوری هایی که یک توسعه دهنده دات نت باید بداند راهنمایی کند از جمله
Blazor، .NET MAUI، gRPC، GraphQL، SQL Server، Cosmos DB، OData، OData،
SignalR، Azure Functions.
There is a lot of promise in bringing Blazor goodness to WPF desktop apps. This would be a wonderful way to modernize WPF apps and share code better between web/desktop.
In 16.7 Preview 4, we added the new Razor editor for local development with MVC, Razor Pages, and Blazor. The new Razor editor has a ton of new tooling support surpassing the functionality of the existing editor.
Welcome to the emerging new world of Microsoft-centric software development. Want to code a desktop app? Take your tooling pick from WPF, WinForms, UWP, .NET MAUI, Win UI, Blazor, Project Reunion ... and who knows what's next.
